UNITED STATES ALBERT B. WOIECXENER, OF ROCK ISLAND, ILLINOIS.

MUSIC-LEAF TURNER.

Application led December 17, 1923.

To all whom t may concern:

Be it known that I, ALBERT B. TonennNnn, a citizen of the United States, residing at Rock Island, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Music-Leaf Tui-ners; and I do declare the following to. be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The principal object of my invention is to provide a music leaf turner' by the use of which, a"plurality of holders for leaves of music may be successively carried from retaining means on a music rack or stand, to receiving means on said rack or stand, and turned during their movement from the one position to the other, the construction being such that the musicians hands are free for use upon his instrument.

Other objects are to provide the retaining means, the receiving means, the sheet holders and their carrying means, and all other' parts, in simple yet effective and durable forms.

A still further object is to provide for easily attaching the turning means to and detaching it from the music stand or rack.

Vith the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompany- .ing drawings.

Figure l() vis a plan view of one of the sheet holders.

Figure il is a sectional perspective view showing the gripping means with which the carrier is provided, to engage the sheet holders.

Briefly described, the invention comprises retaining means R for a plurality of music sheet holders Il, receiving means It' 'to suecessively receive the holders H, a sheet carrier C having gripping means G for gripping the holders II successivelyT and bodily carrying them into engagement with the receiving means R, and releasing means for said gripping means. These numerous elements of the invention may take form in numerous ways, but the construction specifically described below is preferable. Also, although I have shown the invention in connection with a music rack fr of a music stand S, it will be understood that it may be used in connection with other forms of racks or supports for the sheets of music to be turned.

In the construction disclosed, an elongated bar l has been shown, carrying the music-turning means and provided at its ends with hooits 2 for passage around the. ends of the rack fr, the upper edge of said bar l being provided with projecting lingers 3 which may be pivotally mounted if desired, said iingers being adapted to abut the upper edge of the rack and hold the bar 1 against downward sliding. This mounting of the bar l permits it to be readily attached to the rack or detached therefrom, as occasion may require.

The retaining means It has been shown as consisting of pairs of pins fl and 5 extending forwardly from the right-hand end of the bar' l, while the receiving means R has been shown as consisting of a pair of curved pins (5 in the same-plane with the pins i, saidpins G being projected from the other end of the bar l.

The holders H for the sheets of music have been shown in the form of elongated plates having suitable clips T for attaching them to the upper edges of the sheets, each holder being formed with a pair of openings 8 to first receive the pins et as shown in Figs. 1, 2 and 3 but to later receive the pins 6, as disclosed in Fig. 5. I have shown the upper edge of each holding plate provided with an upstanding flange 9 which is clinched at 1() around the intermediate portion of a length of wire, the ends 11 of this wire being extended beyond the fiange 9, so as to provide each of the sheet holders with a pair of gripping pins. One pin of each holder is intended to be gripped by the gripping means G and it will be seen that providing each holder with a pair of these pins 11, makes such holder reversible so that it cannot be erroneously applied. Attention may here be directed to the fact that the pins 5, above referred to, loosely engage the upper portions of the flange 9 and assist in retaining the holders H in proper position.

The carrier C is by preference in the form of a pivoted arm including inner and outer sections l2 and 13 which are relatively movable. In the construction shown (see Figs. 6 and 7), the inner arm section 12 is formed with a longitudinal guide slot 14 in which the outer section 13 is slidably received, a coiled spring 15 being housed within said section 12 to normally project the section 13. This last named section carries the gripping means G and is preferably in the form of a fiatspring, as shown.

The arm section 12 has been illustrated, as being detachably mounted upon a suitable bracket 16 which is in turn detachably connected at 17 with a block 18 at the center of the bar l. The pivoted end of this arm section is provided with a pulley portion 19 with which a suitable spring 19 is associated to normally throw the carrier C toward the right, to the position shown in Figs. 1, 2 and 3. An ope-rating cable 20 however is engaged with the pulley 19, passes through notches 21 in the parts 18 and 1, and is trained around a suitable guide sheave 22 carried by said part 18. The lower end of the cable 2O is secured to a suitable foot pedal 23 connected with the st-and S in any desired manner, so that by depressing this pedal, the carrier C will be swung to the position disclosed in Fig. 5, while release of said pedal, will permit the carrier to return to its original position, as disclosed for instance in Fig. 1.

The gripping means G, in the construction shown, includes a housing 24 carried by the outer end of the arm section 13, said housing having a throat 25 to receive the pins 11 of the holders H. Within the housing 24, a pair of gripping aws 26 have been shown, said jaws having notches 27 in their inner edges to grip the pins 11. I have shown the housing 24 as formed with open sides at the outer edges of the jaws 26 and have illustrated a U-shaped spring 28 straddling the housing with its arms disposed at said open sides and engaged with the jaws 26, so as to yieldably force these jaws inwardly toward each other, yet to allow them to separate whenever the throat 25 receives one of the pins 11.

lVhen the holders H are engaged with the receivin means R, the outer section 13 of the carrier C is slid inwardly as disclosed in Fig. 5, whereby to withdraw the gripping means G from the pin 11 previously held, so as to leave the holder engaged with said receiving means and permit the carrier C to return to the stack of holdels in the retaining means R to grip the next holder. To slide the section 13 in this manner, I have shown an arm 29 pivoted to the arm section 12 and connected by a flexible connection 30 with the outer arm section 13, said connection 30 being by preference engaged with a suitable guide sheave 31 on the arm section 12. I have shown the arm 29 )rovided with a lateral. projection 32 an in the path of this projection, a stationary stop 33 is provided on the bar 1. Thus, about the time the sheet holder H is engaged with the receiving means R', the projection 32 strikes the stop 33 as disclosed in Figs. 4 and 5, thus causing a swinging of the arm 29, a consequent pull upon the connection 30, and inward sliding of the arm section 13, so that the gripping means G is withdrawn from the pin 11 previously held thereby.

Projection of the arm section 13 to an excessive extent, is prevented by a lateral finger 34 on an auxiliary arm 35 which extends from the arm section 12, along the arm section 13. This same finger prevents movement of the holder H with the outer section 13, as t-he latter starts toward the arm section 12, as will be seen by reference to Fig. 4. Also, by referring to Fig. 2, it will be seen that the finger 34 acts as a feeler to strike the foremost of the holders H held by the retaining means R, so as to relatively position the gripping means and the holder, incident to engagement of the one with the other.

The operation of the device is as follows: The sheets of music to be turned, are provided with the holders H and the latter have their openings 8 passed over the pins 4, so that a stack of the-m is held by these pins. The carrier C which has been held in a forward position, is now released and its spring 19 moves it to the right, so that the jaws 26 grip the foremost of the pins 11. When now, the pedal 23 is depressed, the carrier C is swung to the left causing the gripping means G to carry with it, the foremost of the holders H. If the pedal 23 is depressed to the maximum, the carrier C swings entirely over to the left and the holder is deposited upon the pins 6, the gripping means being released y from the pin 11, by movement of the arm 29, when it encounters the stop 33. If the pedal is not entirely depressed, it will be seen that the carrier C may be stopped in t-he position disclosed in Fig. 4 and consequently the holder H may be returned to the retaining means R, if this should be necessary, for instance, to again play the notes on one side of the sheet held by said holder.

A device constructed as, or substantially as shown and described, has proven to be highly efiicient and desirable and as excellent results are obtainable from the present disclosure, the details shown may well be followed. However, it will be understood that within the scope of the invention as claimed, the device may be embodied in a great number of forms.
